Philodendron gloriosum x pastazanum 'Dean McDowell', commonly referred to simply as Dean McDowell, is a highly sought-after hybrid within the Philodendron genus. This hybrid is the result of crossing Philodendron gloriosum and Philodendron pastazanum, two species known for their stunning foliage. 'Dean McDowell' combines the best traits of both parents, featuring large, heart-shaped leaves with prominent veining and a velvety texture, making it a prized addition to any tropical plant collection.
Morphological Characteristics:
-
Leaves: The leaves of Philodendron gloriosum x pastazanum 'Dean McDowell' are its most striking feature. They are large, heart-shaped, and can grow up to 60 cm (24 inches) or more in length. The foliage has a velvety texture, characteristic of Philodendron gloriosum, with deep green coloration that may exhibit a slightly bluish tint. The leaves are adorned with prominent, white to light green veins that create a beautiful contrast against the darker leaf surface. The shape of the leaves is more reminiscent of Philodendron pastazanum, with a broad, rounded heart shape and slightly undulating edges. New leaves typically emerge with a lighter green or slightly reddish hue before maturing into their darker, velvety form.
-
Stems: The stems of Philodendron gloriosum x pastazanum 'Dean McDowell' are thick, sturdy, and usually green with a hint of red or burgundy, especially near the petioles. The petioles (leaf stalks) are long and robust, supporting the large, heavy leaves and contributing to the plant’s semi-upright, spreading growth habit. The stems may also develop aerial roots, which can help the plant anchor itself if allowed to grow horizontally along the ground or a substrate.
-
Growth Habit: Philodendron gloriosum x pastazanum 'Dean McDowell' has a creeping or sprawling growth habit, similar to its parent Philodendron gloriosum. It is a terrestrial grower, meaning it tends to spread horizontally rather than climbing like many other philodendrons. The plant’s moderate growth rate and large, dramatic leaves make it an excellent choice for floor displays, where its striking foliage can be fully appreciated. Over time, it can spread across the soil surface, producing new leaves along its rhizome.
Ecological Preferences:
-
Light: Philodendron gloriosum x pastazanum 'Dean McDowell' thrives in bright, indirect light. It can tolerate lower light conditions, but providing brighter, filtered light will encourage more vigorous growth and better coloration in the leaves. Direct sunlight should be avoided, as it can cause the velvety leaves to scorch. If grown indoors, placing the plant near an east or north-facing window with filtered light is ideal.
-
Soil: This hybrid prefers a well-draining, airy soil mix that retains moisture without becoming waterlogged. A mix of peat moss, perlite, and orchid bark is ideal, providing both the moisture retention and aeration needed for healthy root development. The soil should be kept consistently moist but not soggy, as philodendrons are prone to root rot if left in overly wet conditions.
-
Water: Water Philodendron gloriosum x pastazanum 'Dean McDowell' when the top 2-3 cm of soil feels dry. The plant enjoys consistent moisture, especially during the growing season (spring and summer), but care should be taken to avoid overwatering. During the dormant period (fall and winter), reduce watering frequency slightly, allowing the soil to dry out more between waterings.
-
Humidity: This plant thrives in high humidity levels, ideally between 60-80%. Higher humidity helps maintain the lush, velvety texture of the leaves and prevents the edges from browning. Using a humidifier, placing the plant in a bathroom, or regularly misting the plant can help maintain optimal humidity indoors.
-
Temperature: Philodendron gloriosum x pastazanum 'Dean McDowell' prefers warm temperatures, ideally between 18-26°C (65-80°F). It is sensitive to cold drafts and should be protected from temperatures below 15°C (59°F). Consistent warmth and stable conditions will help keep the plant healthy and encourage continuous growth.
Additional Care Tips:
-
Fertilization: Feed Philodendron gloriosum x pastazanum 'Dean McDowell' with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season. A fertilizer formulated for tropical foliage plants is ideal, supporting the development of large, healthy leaves. Avoid fertilizing during the winter months when the plant’s growth naturally slows.
-
Pest Management: This hybrid can be susceptible to common houseplant pests such as spider mites, mealybugs, and aphids. Regularly inspect the plant, particularly the undersides of leaves and along the stems, and treat any infestations promptly with insecticidal soap or neem oil. Maintaining proper watering practices, high humidity, and good air circulation will help reduce the risk of pest issues.
